Circulation Distribution

Background: The heart acting analysis leads to necessity of total energy quantization needful for its life from the cellular metabolism (Keith Flack node). This energy is mainly distributed to make possible the cardiac muscle acting (Electrocardiogram) and to circulate the blood in aorta to be ultimately poured out the small circulation in upstream of general circulation, distribution obeying Lusamba diagram. A model has been elaborated to choose a thermodynamic system (KUNYIMA Chart) on which the needful energy of blood flow has been assessed. It stays to quantify the vital energy for the electrification of cardiac muscle (ECG) in order to have a definitive idea on total energy from Keith Flack node. Each heart failure demands energetic knowledge of Keith Flack node and the energetic repartition of ventricles shrinkages. Aim and Objective: Presentation master program in cardiochemistry (new discipline) and Lusamba diagram to scientific world. Methodology: Observation, documentary research and calculations have been used. Results: Physico-chemical and thermoexergetic grounds of heart acting have been published elsewhere and allowed thus to conceive this program. Conclusion: Physical Cardiochemistry (PCC) is therefore a set of physico-chemical and thermoexergetic grounds of heart acting. It backs up the bio-medical sciences and helps in one sense to the comprehension of certain energetic phenomena occurring in the cardiac system. Therefore, this large knowledge will help physicians to efficient prescriptions for an effective energetic and appropriate supplying. It is supposed evidently that future cardiac healing will essentially be energetic.

Long Time

The urgency of the study is based on the fact that for a long time, there have been disputes in the scientific world about methods and models for determining the value of prices, on the basis of which the economic accessibility of various kinds of organic products depends. It is especially important to resolve the issue of setting prices for agricultural cooperatives, which have developed in the Russian market economy. The purpose of the study is to find a method for setting wholesale prices for organic products, the consumer demand for which has increased over the past two years and exceeded the level established by the Russian Academy of Medical Sciences. The following methods were used in the study: analytical, systemic, comparative, economic and mathematical, hypothetical, questionnaires, etc. The study conducted an excursus into the field of basic theories of determining prices created by scientists, on the basis of which it was concluded that there is no single approach to determining their values. The prices for organic agricultural products sold by large retailers are analyzed. Using a sample of closest prices of various agricultural producers, average wholesale prices for agricultural products were determined for three regions of the Central Federal District. As a result of the conducted study, the wholesale price for organic agricultural products (on the example of potatoes) purchased by wholesale distribution centers providing the needs of the population of Moscow and the Moscow region was substantiated.

Physico-chemical (pH, conductivity, dissolved oxygen, alkalinity, hardness, nitrogen, heavy metal, etc) and bacteriological (coliform bacteria) characteristics of water were studied in samples collected from Sundarijal reservoir and its main feeding streams: Bagmati, Nagmati and Shyalmati in 2003 and 2004 AD. Human activities near the water bodies and sanitary condition of the residential areas of watershed were also examined. Although public awareness and proper management of watershed and reservoir premises were lacking, yet the physico-chemical characters were within the standard of World Health Organization (WHO) and European Commission (EC) for drinking water. However, the coliform bacteria were high and water was not safe to consume without intense treatments with disinfectants.

Open Thermodynamic System

The absorption and dispersion of sound due to dissipative phenomena such as diffusion, heat conduction and viscous flow have been investigated by Herzfeld, Litovitz and others. Whereas in these studies the total energy of the carrier system remains constant, we consider the case that it is changing. It turnes out that the wavelength X remains constant, while all other wave characteristics become time depend and can be connected with the usual sound velocity of the carrier system ..The change in energy density takes place via the potential energy. Thus the original balance between potential and kinetic energy is disturbed. Modulation vibrations of the wave amplitudes around the time averages arise. In addition dephasing of the pressure and density components with respect to the acoustic velocity takes place. The phasevelocities are disturbed too. They differ from time dependence of c(t).These differences are running asymptotically towards zero, i. e. after a longer period of time a phase step remains of the total wave system. This phase step is negative for increasing energy of the carrier system and positive for decreasing energy. The value of the phase step is proportional to the wavelength λ, i. e. systems of this kind show dispersion.

The total energy involved in emplacing a thrust sheet is expended in initiation and growth of the thrust surface, slip along this surface, and deformation within the main mass of the sheet. This total energy can be determined from potential energy considerations knowing the initial and final geometry from balanced cross sections after defining the thrust’s thermodynamic system boundaries. Emplacement of the McConnell thrust in the Canadian Rockies involved ca. 1019 J of gravitational work, an order of magnitude greater than any possible work by longitudinal compressive surface forces. A new theory for the initiation and growth of thrusts as ductile fractures is based on a demonstration that thrust displacement is linearly related to thrust map length and that fold complexes at the ends of thrusts are constant in size for a given metamorphic grade. Much of the total work is dissipated within the body of the sheet. Field observations show which mechanisms of dissipation are most important at various positions within the thrust sheet, and it is found that only the top 5 km of the McConnell was dominated by frictional sliding. A novel type of sliding along discrete surfaces is pressure solution slip, in which obstacles are by-passed by diffusive mass transfer. Fibres and pressure solution grooves are diagnostic features of this sliding law, in which slip velocity is linearly related to shear stress. Pressure solution slip is widespread at depths greater than about 5 km, but at this depth penetrative whole rock deformation by pressure solution becomes dominant - marked by cleavage and stretching directions - and accounts for much of the finite strain within the thrust sheet. The McConnell thrust has an outer layer which deformed by frictional sliding and this overlies a massive linearly viscous core responsible for much of the energy dissipation and gross mechanical behaviour.

Abstract The total potential energy of the atmosphere is the sum of its internal and gravitational energies. The portion of this total energy available to be converted into kinetic energy is determined relative to an isothermal, hydrostatic, equilibrium atmosphere that is convectively and dynamically “dead.” The temperature of this equilibrium state is determined by minimization of a generalized Gibbs function defined between the atmosphere and its equilibrium. Thus, this function represents the maximum amount of total energy that can be converted into kinetic energy and, hence, the available energy of the atmosphere. This general approach includes the effects of terrain, moisture, and hydrometeors. Applications are presented for both individual soundings and idealized baroclinic zones. An algorithm partitions the available energy into available baroclinic and available convective energies. Estimates of the available energetics of the general circulation suggest that atmospheric motions are primarily driven by moist and dry fluxes of exergy from the earth’s surface with an efficiency of about two-thirds.

AbstractThe total energy flux leaving the ocean’s spatially and seasonally varying mixed layer is estimated using a global ⅝1/10° ocean general circulation model. From the total wind-power input of 3.33 TW into near-inertial waves (0.35 TW), subinertial fluctuations (0.87 TW), and the time-mean circulation (2.11 TW), 0.92 TW leave the mixed layer, with 0.04 TW (11.4%) due to near-inertial motions, 0.07 TW (8.04%) due to subinertial fluctuations, and 0.81 TW (38.4%) due to time-mean motions. Of the 0.81 TW from the time-mean motions, 0.5 TW result from the projection of the horizontal flux onto the sloped bottom of the mixed layer. This projection is negligible for the transient fluxes. The spatial structure of the vertical flux is determined principally by the wind stress curl. The mean and subinertial fluxes leaving the mixed layer are approximately 40%–50% smaller than the respective fluxes across the Ekman layer according to the method proposed by Stern. The fraction related to transient fluctuations tends to decrease with increasing depth of the mixed layer and with increasing strength of wind stress variability.

Abstract. A global multicompartment model which is based on a 3-D atmospheric general circulation model (ECHAM5) coupled to 2-D soil, vegetation and sea surface mixed layer reservoirs, is used to simulate the atmospheric transports and total environmental fate of dichlorodiphenyltrichloroethane (DDT) and γ-hexachlorocyclohexane (γ-HCH, lindane). Emissions into the model world reflect the substance's agricultural usage in 1980 and 1990 and same amounts in sequential years are applied. Four scenarios of DDT usage and atmospheric decay and one scenario of γ-HCH are studied over a decade. The global environment is predicted to be contaminated by the substances within ca. 2 a (years). DDT reaches quasi-steady state within 3–4 a in the atmosphere and vegetation compartments, ca. 6 a in the sea surface mixed layer and near to or slightly more than 10 a in soil. Lindane reaches quasi-steady state in the atmosphere and vegetation within 2 a, in soils within 8 years and near to or slightly more than 10 a and in the sea surface mixed layer. The substances' differences in environmental behaviour translate into differences in the compartmental distribution and total environmental residence time, τoverall. τoverall≈0.8 a for γ-HCH's and ≈1.0–1.3 a for the various DDT scenarios. Both substances' distributions are predicted to migrate in northerly direction, 5–12° for DDT and 6.7° for lindane between the first and the tenth year in the environment. Cycling in various receptor regions is a complex superposition of influences of regional climate, advection, and the substance's physico-chemical properties. As a result of these processes the model simulations show that remote boreal regions are not necessarily less contaminated than tropical receptor regions. Although the atmosphere accounts for only 1% of the total contaminant burden, transport and transformation in the atmosphere is key for the distribution in other compartments. Hence, besides the physico-chemical properties of pollutants the location of application (entry) affects persistence and accumulation emphasizing the need for georeferenced exposure models.

Abstract Tadeusz Stefan Kurkiewicz (1885-1962) belongs to the well-known Polish histologists and embryologists. His scientific activity started in the Department of Biology and Embryology of the Jagiellonian University in Cracow, which was chaired by professor Emil Godlewski (1875-1944), famous Polish embryologist. Between years 1908-1911, under supervision of the pioneer of the Polish histology, professor Stanisław Maziarski (1873-1959) T. Kurkiewicz continued researches in the Department of Histology of the Jagiellonian University. In 1909 he published results of studies on the development of cardiac muscle in the chick and on the basis of this publication on July 21, 1911 Tadeusz Kurkiewicz received Ph.D. from the Jagiellonian University. Between 1922 and 1959 (with the exception of the period of German occupation) Tadeusz Kurkiewicz was the head of the Department of Histology and Embryology of the Faculty of Medicine of the Poznań University and Academy of Medicine in Poznań (at present: Poznań University of Medical Sciences). His Ph.D. thesis demonstrated that the epicardium originates from pericardial villi, it means from extracardiac source. This great scientific achievement has been confirmed by recent studies. In this article we present curriculum of Tadeusz Kurkiewicz and impact of his discovery on contemporary cardiology.

Imidazole and its derivates represent an interesting source of study for researchers for more than a century and was recently studied for their analgesic effect by ORL-1 receptor agonist effect on. In the theoretical study we used molecular mechanics programs and we characterized the structural properties for a series of ten imidazoles. The selected physico-chemical descriptors were: the HOMO and LUMO frontier orbitals, the dipole moment, the heat of formation, the total energy of the molecule, the ionization energy, the surface area and the molecular volume. From the correlation study we noticed the dependence between the analgesic effect and the total energy, the area of the molecular surface and the molecular volume.

The researcher’s approaches to the term “fluid systems” as a prototype of the fluid medium of crystallization of minerals, naturally preserved relics – inclusions of fluids reflect the features of the fluid regime of mineralogenesis of rock-ore complexes are analyzed. It is emphasized that the term “fluid” characterizes the main property of the substance of the medium of mineralogenesis, the most important substance of the Earth’s crust, its highest mobility, the maximum disorder of structure, fluidity, and covers the liquid or gas state of the lightweight components (gas, aqueous solution), as well as the melt of magmatic (silicate, salt, carbonate) substance. Under the fluid regime, the author understands the physical and chemical nature, the spatial-temporal sequence of manifestation and the variability of the parametric characteristics of the fluids, that is, the entire set of physico-chemical and geological phenomena and processes that determine the regular (discrete, periodic, evolutionary) changes in aggregate state, PT-parameters and the composition of the fluid medium of crystallization of minerals and their identified (certain, specific) parageneses. Our long-term studies show that the physico-chemical system of the fluid medium of mineral-ore-narhtidgenesis should cover lithoid (rocky), fluid (genetic) and thermodynamic (temperature, pressure, concentration) components that determine the mass, heat and the energy exchange between the fluid and of its host rock. In view of this, we define this physico-chemical system as a “lithofluid and thermodynamic system” and we believe that this definition takes into account all known phenomena of generation, migration, differentiation and accumulation of fluids, in particular hydrocarbons (hydrocarbon-containing), in the lithosphere of the Earth. An example of such a lithofluid and thermodynamic system in the Earth’s bowels – the natural high-energy physicochemical reactor is the hydrocarbon-generating and mineral-ore-forming system of the deep abiogenic high-termobaric fluid.
